Application filed May 14, 1923. Serial No. 638,764.

ToaZZ whom it may concern:

Be it known that I, JOSEPH O. CHARPEN- TIER, a citizen of the UnitedStates, residing at Concord, in the county of Merrimack and State of NewHampshire, have invented new and useful Improvements'in Scrapers, ofwhich the following is a. specification.

The general object of this invention is to provide an implement adaptedto scrape the ceiling of a room to remove dust and dirt therefrom, andto prepare the ceiling for subsequent treatment, the implement havingmeans for catching and. accumulating the matter removed from theceiling, to prevent such matter from being scattered on the floor.

Particular objects of the invention will appear from the followingspecification, and the novel features will be pointed out inthe appendedclaims.

Of the accompanying drawings forming a part of this specification,

Figure l is a side elevation of a scraper embodying the invention.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is an enlargement of a portion of Figure 2.

Figure l is a perspective view of the dust pan shown by Figures 1 and 2.

Figure 5' is a perspective view of a portion of the handle.

Figure 6 is a perspective view of the scraper-holding plate hereinafterdescribed.

Figure 7 is a perspective view of the scraper.

Figure 8 is a diagrammatic view hereinafter described.

In the drawings, 12 represents an elongated. handle, preferably a woodenrod about six feet long, although the length may be varied. One end ofthe handle is provided with a metal ferrule 1.3, this end and theferrule being provided with a transverse slot 14, best shown by Figure5.

15 represents a scraper-holding plate, preferably of sheet metal,provided with parallel ears 16, overhanging a portion of the body of theplate, and forming therewith channels adapted to receive opposite endsof a scraper 17. The scraper is an oblong metal plate having scrapingedges 18, which constitute the opposite edges of the plate and areadapted to be used interchangeably, as hereinafter described. The sidesof the plate may be beveled to reduce the thickness of the edges 18, orsaid edges maybe of the full thickness of the plate, and kept sharp bygrinding off their surfaces from time to time, to keep the edges 18 atright angles with the sides of the plate.

The scraper is detacha-bly secured to the holding plate 15 by means of atongue 19, formed on or attached to a spring shank 20, the resilience ofwhich causes it to press the tongue 19 into coinciding slots 21 and 22,formed respectively in the scraper and the holding plate 15.

The rear end portions of the holding plate 15 and of the spring shank 20are inserted in the handle slot 14:, and secured therein by one or morerivets 23, as best shown by Figure 3.

24 represents a dust pan, to the back of which is secured a cylindricaltubular socket 255, by a shank 26, which is soldered, or otherwisesecured to the back of the pan. The socket 25 has a close frictional fiton the handle 12, and is adapted both to turn and move endwise on thehandle, the frictional fit holding the socket in any position to whichitma be moved on the handle.

The arrangement is such that when the scraper is applied to a ceiling byan operator standing on the floor and manipulating the handle 12,the'dust pan is located under the scraper and in position to catchmatter removed from the ceiling by the scraper. Owing to the fact thatthe socket is adapted to turn on the handle, the pan bottom may standsubstantially parallel with the scraper, or may be inclined relative tothe scraper, as shown diagrammatically by Figure 8, thus enabling oneend of the scraper to enter the corner between a ceiling and a verticalwall 28, the pan bottom being inclined relative to the scraper and oneend of said bottom being imder the end of the scraper which is adjacentto the wall 28.

Owing to the fact that the socket is adapted to move endwise on thehandle, the pan bottom may be adjusted so that its forward edge isdirectly under the forward edge of the scraper and adapted to catchmatter falling therefrom, when the handle is held at differentinclinations, the pan being adjusted outward when the handle is held atThediesoribed means for detachablycom neoting the soraper With thehandleen-ablesa two-edged scrapert0b8v employed, the edges of. which areadapted to be used interchangeably, so that When one edge be.- comesdull, the scraper may be reversed and the opposite edge utilized Iclaim:
